Description
Rugged Obsidian Piston
The Rugged Obsidian Piston with 16×1 LH thread pattern; 17-4 stainless steel construction; and copper finish.
Rugged Suppressors is proud to offer this piston that will make your shooting experience more enjoyable, thanks to its non-slotted design which creates a full circumference gas seal, causing gas blowback to be drastically lowered.
Machined from 17-4 stainless steel as well as heat treated, the Obsidian 16×1 LH Piston comes extremely durable.
*When using a piston on a fixed barrel platform such as a carbine or subgun the spring must be replaced with a fixed barrel spacer.
